Capturing MiniDV through the SONY M15 VCR.

Hi,
The SONY M15 is a VCR player/recorder of MiniDV, HDV, DVCAM, etc. I wonder if I want to capture to the computer, will be enough the firewire connection? or do I also need to connect S video Out, audio an a converter like the Canopus?

Other thing: the video components out, should I use them to capture video to the computer?
